By taking cod liver oil supplements, people intake an abundant supply of Vitamin D, regardless of whether they get sufficient sunlight (there are many other reasons to seek natural sunlight, however, since phototherapy and light therapy both have significant health benefits just now being recognized).
The only real concern about cod liver oil has been the contamination of oil sources (the fish) with PCBs and heavy metals. This concern is a legitimate one, and lab tests have shown some supplements to contain rather alarming levels of these toxic contaminants. Without knowing which supplements to trust, some people hesitate on taking the cod liver oil they probably need. The solution? Do what I do: take cod liver oil supplements along with superfood supplements containing large amounts of chlorophyll. Chlorella and spirulina are two of my favorites. Chlorophyll protects the body from toxic metals and helps speed them out of the system (chlorophyll is widely known as a blood cleanser and liver detoxifier). By taking cod liver oil together with chlorella, you get the best of both worlds: omega-3 oils, Vitamin D, plus all the health benefits of chlorella.
Yet another medical triumph for cod liver oil was announced yesterday
(accompanied by the rather forward claim that the later life of the
Queen Mother would have been quite different, had she only imbibed a
daily spoonful as a girl).
The estimated direct cost of arthritis to the health and social
services is approximately �5.5bn a year.
Cod liver oil has bags of vitamin D, and even more vitamin A - more of
the latter per unit weight than any other common food, more than three
times as much, for example, as the next richest source, beef liver - and
it is also a huge source of omega-3 fatty acids.
